model property
Model names the model to run on. Omit it to take the deployment's configured default; name one and it is checked against the gateway's served catalogue here, so a model this deployment cannot serve is refused now rather than at the first run. Stored under our own name for it, whatever spelling arrives.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
String? model;
